First, it looks very nice. Since it's not set in a big city, the director has the chance to use some of the country scenery as a backdrop to the action. Mind you, a lot of the action seems to take place on or around this bridge.
Second, everyone is attractive. I thought I'd got used to how pretty Japanese women can be, but maybe not. I'm up to episode seven, and I still can't work out which one I fancy most. And the men, too, are all handsome outdoors types. Seriously, if this had been the first J-drama I'd seen, I'd definitely want to see more of this.
Then there's the stories. A series of overlapping romantic triangles: that's the easiest way to describe it. It's light-hearted and fun, but there's enough of a social context (the slow decline of the town centre) to make you think that you're not wasting your time on gossipy nonsense.
And I like the theme tune, too.
